The pieces depict a “a universal connection between people and the universe” and are located at the top of and alongside the Terminal 1 Metrolink escalator.

At San Francisco International Airport (SFO), the SFO Museum has a new exhibition about the history of lace from the 1600s to the 1900s.

Included is this fan from the late 1800s.

According to the museum notes, the folding fan originated in Japan and was introduced to Europe in the second half of the sixteenth century as a fashion accessory and “as a subtle tool for flirting with suitors.”

During the Victorian Era, when a woman drew her fan across her cheek it supposedly meant, “I love you.” Fanning slowly meant: “I am married.”

The exhibit – Lace: A Sumptuous History – includes edgings, lappets, parasols, gloves, collars, dresses and more and is on display on the departures level of the International Terminal, pre-security, through June 2014.
